Self-Serve Platform Enables Enterprises to Automate Customer Calls

Bolna provides a self-serve platform that allows businesses to design, deploy, and monitor voice AI agents without lengthy implementation timelines or specialized AI skills 2

2

. According to founder and CEO Maitreya Wagh, approximately 75% of users leverage the self-serve tool for complete control over their agents, while the remaining 25%—including some publicly listed companies—opt for fully forward-deployed services where Bolna builds and deploys agents for them 2

. The company's orchestration layer enables businesses to run multilingual voice AI systems across multiple languages and scenarios on a single platform, designed specifically for high-volume telephony 1

Cost Efficiency and Market Opportunity to Reduce Operational Costs

Bolna's voice AI solution delivers significant cost advantages compared to traditional human call centers. Wagh explained that human callers currently cost around Rs 4-5 per minute, rising to Rs 6-7 per minute when factoring in onboarding, attrition, middle management, recruitment, training, and vacations 2

2

. In contrast, Bolna's end-to-end offering—including telephony, analytics, and infrastructure—costs as little as Rs 2.5 per minute at scale 2

2

. The market potential remains vast: Indian businesses make over a billion calls daily, or approximately 30 billion monthly, yet voice AI currently handles only around 20 million calls per month, of which Bolna processes about two million 2

.

Multilingual Capabilities Across Indian Languages

The platform supports over 10 Indian languages—English, Marathi, Hindi, Gujarati, Tamil, Telugu, Kannada, Malayalam, Urdu, and Bengali—serving customers across more than 10 countries with India as its primary market 2

. Tom Blomfield, group partner at Y Combinator, noted that "India has 22 official languages and hundreds of dialects. Building voice AI that actually works here is a hard problem, and they were solving it while generating revenues" 2

. The company enables high-volume voice processing for specialized, voice-dependent sectors such as travel and matrimonial services where multilingual voice interactions serve as the primary communication mode 1
